ISL9208
Multi-Cell Li-ion Battery Pack OCP/Analog
Front End
The ISL9208 is an overcurrent protection device and analog
front end for a microcontroller in a multi-cell Li-ion battery
pack. The ISL9208 supports battery pack configurations
consisting of 5-cells to 7-cells in series and 1 or more cells in
parallel. The ISL9208 provides integral overcurrent
protection circuitry, short circuit protection, an internal 3.3V
voltage regulator, internal cell balancing switches, cell
voltage monitor level shifters, and drive circuitry for external
FET devices for control of pack charge and discharge.
Selectable overcurrent and short circuit thresholds reside in
internal RAM registers. An external microcontroller sets the
thresholds by setting register values through an I
2
C serial
interface. Internal registers also contain the detection delays
for overcurrent and short circuit conditions.
Using an internal analog multiplexer the ISL9208 provides
monitoring of each cell voltage plus internal and external
temperature by a separate microcontroller with an A/D
converter. Software on this microcontroller implements all
battery pack control functionality, except for overcurrent and
short circuit shutdown.

Features
Software selectable overcurrent protection levels and
variable protect detection times
- 4 discharge overcurrent thresholds
- 4 short circuit thresholds
- 4 charge overcurrent thresholds
- 8 overcurrent delay times (Charge)
- 8 overcurrent delay times (Discharge)
- 2 short circuit delay times (Discharge)
Automatic FET turn-off and cell balance disable on reaching
external (battery) or internal (IC) temperature limit.
Automatic override of cell balance on reaching internal
(IC) temperature limit.
Fast short circuit pack shutdown
Can use current sense resistor, FET r
DS(ON)
, or Sense
FET for overcurrent detection.
Four battery backed software controlled flags.
Allows three different FET controls:
- Back-to-back N-Channel FETs for charge and discharge
control
- Single N-Channel discharge FET.
- Single N-Channel FET for discharge, with separate,
optional (smaller) back-to-back N-channel FETs for
charge.
Integrated Charge/Discharge FET Drive Circuitry with
200μA (typ) turn-on current and 150mA (typ) Discharge
FET turn-off current.
10% Accurate 3.3V voltage regulator (minimum 25mA out
with external NPN transistor having current gain of 70).
Monitored cell voltage output stable in 100μs.
Internal Cell balancing FETs handle up to 200mA of
balancing current for each cell (with the number of cells
being balanced limited by the maximum package power
dissipation of 400mW).
